I completely agree that you cannot check this flop. Any continuation bet villain makes commits him if you check/raise allin. However, I think pushing makes it seem like you want villain to fold b/c either you're weak or on a draw. An alternative line here could be to bet 1600-2000. This would send the message to villain that you are not folding, and in fact you are looking for a call. I think this bet may have more folding equity than the all-in push (provided villain is capable of folding AK on a ragged board).
